March 12 (UPI) -- Police in Austin, Texas, said Monday three deadly explosions that targeted three homes this month may be related -- and warned residents to be cautious of suspicious packages left on their doorsteps.

A 75-year-old woman was injured by a third explosion after she walked outside her home in southeast Austin and found a package at 11:50 a.m. Monday.

She was in critical, but stable condition with life-threatening injuries following the blast.
